What Fish To Put With Guppies – Your Ultimate Guide To A Thriving
So, you’ve fallen in love with guppies! It’s easy to see why. These vibrant, active little fish bring so much life and color to an aquarium. They’re hardy, fascinating to watch, and perfect for aquarists from beginners to seasoned hobbyists. But once you have your lovely guppies, a common question quickly arises: “What fish to put with guppies?”
Don’t worry—this is a fantastic question, and getting it right is key to a peaceful, healthy, and bustling community tank. We’ve all been there, staring at the rows of fish at the local fish store, wondering who will get along. The good news? With a little knowledge and planning, you can create a beautiful environment where your guppies and their tank mates truly thrive. Let’s dive in and discover the perfect companions for your dazzling guppies!
Understanding Your Guppies: The Key to Happy Tank Mates
Before we start stocking our tank, it’s crucial to understand the stars of the show: your guppies! Knowing their needs and temperament is the first step in choosing compatible tank mates.
Guppy Temperament and Behavior
Guppies (Poecilia reticulata) are generally known for being incredibly peaceful and active fish. They love to explore, swim, and interact, often occupying the top and middle layers of the aquarium.
They’re also schooling fish, meaning they feel most secure and display their best behavior when kept in groups of at least three, though five or more is even better. This social nature makes them excellent candidates for a community tank.
Ideal Water Parameters
Guppies are quite adaptable, but they truly flourish in stable, clean water conditions. They prefer slightly harder, alkaline water with a pH between 7.0 and 8.0.
Temperature-wise, they are tropical fish, happiest between 72-82°F (22-28°C). Consistency is far more important than hitting an exact number, so a reliable heater is a must.
Guppy Tank Size Requirements
While small, guppies still need adequate space. A minimum of a 10-gallon tank is recommended for a small group of guppies.
However, if you’re planning a community tank, a 20-gallon long or larger is much more suitable. This provides ample swimming space and helps dilute waste, contributing to better water quality for all inhabitants.
The Livebearer Factor
Guppies are livebearers, meaning they give birth to live, free-swimming fry rather than laying eggs. This is a significant factor!
If you have both males and females, you will have baby guppies. Be prepared for this, as it can quickly lead to overpopulation. Maintaining a male-to-female ratio of 1:2 or 1:3 can help reduce stress on females and manage population growth, but it won’t stop it entirely.
Essential Compatibility Factors for Guppy Tank Mates
Choosing the right tank mates isn’t just about picking fish you like. It’s about creating a harmonious ecosystem where every creature can thrive without stress or aggression.
Temperament Match
This is perhaps the most critical factor. Peaceful fish should only be housed with other peaceful fish.
Introducing aggressive or semi-aggressive species to a guppy tank is a recipe for disaster, often resulting in stressed, injured, or even dead guppies. Always aim for species with similar calm dispositions.
Size Considerations
A good rule of thumb in fish keeping is: if it fits in another fish’s mouth, it’s a potential snack. Guppies are small, and their fry are even tinier.
Avoid any fish large enough to view your guppies (or their babies) as food. Conversely, very tiny, timid fish might be stressed by the guppies’ active nature.
Water Parameter Alignment
All fish in your community tank should ideally share similar water parameter requirements (pH, hardness, temperature). Trying to accommodate fish with vastly different needs can lead to chronic stress and disease for one or more species.
Fortunately, many popular peaceful community fish share similar needs to guppies.
Activity Levels and Tank Zones
Consider where fish spend their time in the tank. Some fish prefer the bottom, others the middle, and some the top.
A good community tank has inhabitants that utilize different parts of the water column. This reduces competition for space and resources, leading to a more balanced and interesting display.
Fin Nippers and Long Fins
Guppies, especially the males, are famous for their long, flowing caudal (tail) fins. These beautiful fins can be tempting targets for fin-nipping species.
Even relatively peaceful fish, if known for nipping, should be avoided to prevent stress and injury to your guppies. Always check a species’ reputation for nipping before adding it to your guppy tank.
Top Picks: What Fish to Put with Guppies for a Harmonious Aquarium
Now for the fun part! Based on all the compatibility factors, here are some of our top recommendations for tank mates that will happily coexist with your guppies.
Bottom Dwellers
These fish are fantastic because they occupy a different zone of the tank, cleaning up uneaten food and adding a new dimension to your aquarium.
- Corydoras Catfish (Cory Cats): These small, peaceful, and endearing schooling fish are perfect. Species like the Panda Cory, Pygmy Cory, or Bronze Cory are excellent choices. They need to be kept in groups of at least 6 and will happily scavenge the substrate without bothering your guppies. They love clean, sandy bottoms.
- Otocinclus Catfish (Oto Cats): If you’re looking for a natural algae eater, Otos are your best bet. They are tiny, peaceful, and prefer to cling to plants, glass, and decor, grazing on biofilm and soft algae. Like Corys, they are schooling fish and need to be in groups of 6 or more. Ensure your tank is well-established before adding Otos, as they need mature algae growth to thrive.
Mid-Water Schoolers
These fish will complement your guppies’ activity in the middle of the tank, adding more color and movement.
- Neon Tetras & Cardinal Tetras: These iconic schooling fish are a classic choice. Their vibrant colors look stunning against guppies, and their peaceful nature makes them ideal tank mates. They do best in schools of 6 or more.
- Ember Tetras: A smaller, equally peaceful alternative to Neons, Ember Tetras have a beautiful orange-red hue. They are perfect for smaller community tanks and are excellent with guppies. Keep them in groups of 8-10 for best effect.
- Harlequin Rasboras: With their striking copper bodies and unique triangular marking, Harlequin Rasboras are another superb choice. They are calm, hardy, and thrive in schools of 6 or more.
- Chili Rasboras (Boraras brigittae): These are tiny, stunning microfish, perfect for smaller guppy tanks (10-15 gallons). Their bright red coloration is captivating, and their peaceful nature makes them great companions. Keep them in large schools (10+) for security.
Other Livebearers
These fish share similar water parameter needs and generally get along well, but remember the breeding potential!
- Platies: Platies are very similar to guppies in terms of care and temperament. They come in a dazzling array of colors and patterns. They are peaceful and make excellent tank mates. Just like guppies, they are livebearers, so be prepared for fry.
- Mollies: Mollies are another popular livebearer. They are generally peaceful but can sometimes be a bit more boisterous than guppies or platies. They also prefer slightly higher salinity, so ensure your guppies are accustomed to that if you plan to keep them together. Ensure you have plenty of space, as some molly varieties can get quite large (up to 4-5 inches).
Unique Companions
Looking for something a little different? These options can add character to your guppy tank.
- Dwarf Gourami (single male): A single male Dwarf Gourami can be a beautiful addition. They are generally peaceful, especially the males, but can sometimes be territorial towards other males or similar-looking fish. Stick to one male, and ensure the tank is large enough (20 gallons minimum) with plenty of plants for hiding spots.
- Amano Shrimp: These hard-working shrimp are fantastic algae eaters and completely peaceful. They won’t bother your guppies, and your guppies won’t bother them. They’re a great clean-up crew!
- Cherry Shrimp (Neocaridina davidi): These colorful little shrimp are popular for their vibrant hues. Guppies can eat baby cherry shrimp, but adult shrimp are generally safe. If you want to breed cherry shrimp successfully, a dedicated shrimp tank is better. However, a well-planted tank with plenty of hiding spots can allow some shrimp to survive and reproduce with guppies.
Fish to Avoid with Guppies (And Why!)
Just as important as knowing what fish to put with guppies is knowing which ones to steer clear of. Making the wrong choice can lead to stress, disease, and even death for your beloved guppies.
Aggressive and Fin-Nipping Species
These fish are simply not compatible with the peaceful, long-finned guppy.
- Tiger Barbs: While colorful and active, Tiger Barbs are notorious fin-nippers. They will relentlessly harass and injure your guppies, especially the males with their elaborate tails.
- Siamese Fighting Fish (Betta splendens): Bettas are beautiful, but male bettas are highly territorial and aggressive towards other fish with long, flowing fins, which includes male guppies. While some people claim success in large, heavily planted tanks, it’s generally a high-risk combination not recommended for beginners.
- Most Cichlids: Apart from a few dwarf species like Rams (which have specific water needs), most cichlids are too aggressive or territorial for a peaceful guppy tank. Even smaller cichlids can become problematic.
Large or Predatory Fish
Any fish that can fit a guppy in its mouth will eventually try to.
- Angelfish: While often sold as small juveniles, Angelfish grow large and are cichlids. They will view guppies (especially fry) as food.
- Larger Gouramis (e.g., Pearl Gourami, Gold Gourami): While generally peaceful, these fish can grow quite large and may outcompete guppies for food, or even intimidate them due with their size. They are often best kept with other larger, peaceful community fish.
Very Skittish or Shy Fish
Some fish are simply too timid to thrive with the active, outgoing guppy.
- Some types of Dwarf Cichlids (e.g., Apistogramma): While peaceful for cichlids, many dwarf cichlids prefer very calm, quiet tanks and might be stressed by the constant movement of guppies. Their specific water parameters also often differ from guppies.
Fish with Drastically Different Water Needs
Mismatching water parameters is a recipe for chronic stress and disease.
- Discus or Angelfish (again): These fish prefer warmer, softer, and more acidic water than guppies. Trying to keep them together would compromise the health of one or both species.
- African Cichlids: These fish require very hard, alkaline water and are typically too aggressive for guppies.
Setting Up Your Guppy Community Tank for Success
Choosing the right fish is only half the battle. A properly set up and maintained tank is crucial for the long-term health and happiness of your guppies and their companions.
Tank Size Matters
For a vibrant community tank, always err on the side of larger. A 20-gallon long is a great starting point, but a 29-gallon or 30-gallon breeder offers even more stability and space.
More water volume means more stable water parameters and more room for fish to establish territories, reducing stress.
Filtration and Water Quality
A robust filtration system is essential. A hang-on-back (HOB) filter or a canister filter that provides both mechanical and biological filtration is ideal.
Regular partial water changes (25-30% weekly) are paramount to keeping nitrates low and water parameters stable. Test your water regularly using a reliable liquid test kit.
Aquascaping for Harmony
Thoughtful aquascaping can make a huge difference in a community tank.
- Provide plenty of hiding spots: Live plants (like Java Fern, Anubias, Amazon Swords), driftwood, and caves offer security for all fish, especially shyer species or those lower in the pecking order.
- Break up lines of sight: Tall plants and decor can create visual barriers, preventing more dominant fish from constantly seeing and potentially harassing others.
- Open swimming spaces: Ensure there are still open areas for your guppies and schooling fish to swim freely.
Acclimation Best Practices
When introducing new fish, always acclimate them slowly to prevent shock. The drip acclimation method is highly recommended, especially for sensitive species.
Float the bag to equalize temperature, then slowly add small amounts of tank water to the bag over an hour or more, allowing the fish to adjust to your water parameters.
Monitoring and Maintenance
A healthy aquarium is an actively monitored one.
- Observe your fish daily: Look for any signs of stress, disease (e.g., clamped fins, white spots, lethargy), or aggression between tank mates. Early detection can save lives.
- Feed a varied diet: High-quality flake food should be supplemented with frozen or live foods like bloodworms, brine shrimp, and daphnia to ensure a balanced diet.
- Perform regular maintenance: Beyond water changes, this includes cleaning filter media, gravel vacuuming, and scraping algae.
Frequently Asked Questions About Guppy Tank Mates
Let’s tackle some of the most common questions hobbyists have when planning their guppy community tank.
Can guppies live with bettas?
Generally, no, it’s not recommended. Male Bettas are known to be aggressive towards other fish with long, flowing fins, which includes male guppies. While some experienced aquarists have success in very large, heavily planted tanks with specific betta temperaments, it’s a high-risk combination that often ends in tragedy for the guppies. It’s best to avoid this pairing, especially for beginners.
How many guppies should I have?
Guppies are schooling fish and thrive in groups. Aim for a minimum of three, but five or more is ideal. If you plan to keep both males and females, a ratio of 1 male to 2-3 females is recommended to spread out the males’ attention and reduce stress on the females. Be prepared for prolific breeding if you mix genders!
Can guppies live with shrimp?
Yes, adult guppies can generally live with adult shrimp like Amano Shrimp or larger Cherry Shrimp. However, guppies will almost certainly eat baby shrimp (fry). If you want to successfully breed shrimp, a dedicated shrimp tank is best. In a heavily planted community tank, some baby shrimp may survive by hiding.
What about snails?
Most common aquarium snails (e.g., Nerite snails, Mystery snails, Ramshorn snails) are excellent tank mates for guppies. They are peaceful, non-aggressive, and help with algae and detritus cleanup. They won’t bother your guppies, and your guppies won’t bother them.
Do guppies need a heater?
Yes, guppies are tropical fish and need stable water temperatures, typically between 72-82°F (22-28°C). A reliable aquarium heater with a thermostat is essential to maintain these conditions and prevent temperature fluctuations, which can stress your fish and make them susceptible to disease.
